[QUOTE="DidUHearThat?, post: 5020804, member: 594758"] You should wire everything to be correctly phased, positive to positive, until you have a very specific reason to reverse it. A very simple way to check phase on woofers is to, first disconnect the speaker leads from the amp, then touch the speaker leads to a 9 volt battery. With the positive of the battery to the positive speaker wire, the sub should move out and lock in that position. When you reverse the battery the sub should move to its lowest position. You can do this again with your mid/bass speakers to see if they are moving in the same direction.
